thank you.
i do not investigate which baud i could use.
I've tried with 32Mbits and a delay of 50ms between each frame. It works but i take 0.4s (30 percent better) but 2.5 frame/sec.
and with an ugly scanning refresh.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
why so low (1Mbit)? these displays can do much more, 16 or even 32Mbit could work (not sure what is the limit of your board)
